Multiwavelet in comparison with barkel wavelet and 9/7 wavelet in image compression

Abstract

for best performance in image compression, scalar wavelet requires filters that combine a number of desirable properties, such as orthogonality and symmetry. The Multiwavelet is a complete orthonormal and symmetry. Multwavelet shows promise in obviating some of the limitation of wavelet. In this work we compare the Multiwavelt with orthonormal Barkel wavelet, and 9/7 wavelet in image compression performance on 6 gray scale images. A proposed compression algorithm is used, which include the use of Round function and the Run Length Encoding techniques (RLE). The result is obtained in terms of PSNR, and Bit Rate (BitR). Extensive experimental results demonstrate that Multiwavelet methods exhibit performance high to, or in several cases superior to, the other methods in the proposed algorithm. This matches our expectation based on our results that indicate Multiwavelet have the highest result.
